[0055] The pressure sensor 1 comprises: a sensor body 11, a pressure-sensitive diaphragm 12 and a flow rate detection module 13;

[0056] The sensor body 11 includes a base 111, a first support portion 112, a second support portion 113, an annular groove 114 and a first rectangular groove 115; the first support portion 112 and the second support portion 113 are sequentially arranged on the base 111; the first support portion 112 and the second support portion 113 are concentric cylinders, and the diameter of the first support portion 112 is greater than the diameter of the second support portion 113; a cylindrical cavity with an open end is arranged on the outward side of the second support portion 113; the annular groove 114 is concentrically arranged on the top of the second support portion 113 4.

This layered and concentric cylindrical design of the sensor body 11 provides a stable support structure and facilitates the installation and positioning of other components.

[0057] The flow rate detection module 13 includes a support ring 131, a humanoid elastic sheet 132, a second rectangular groove 133 and a strain resistor 134; the support ring 131 is arranged on the outside of the second support portion 113, the outer diameter of the support ring 131 is the same as the outer diameter of the first support portion 112, the inner diameter of the support ring 131 is the same as the outer diameter of the second support portion 113, and the height of the support ring 131 is the same as the height of the second support portion 113; a second rectangular groove 133 (wire groove) is provided on the top of the support ring 131, and the position of the second rectangular groove 133 corresponds to the position of the first rectangular groove 115.

Humanoid elastic sheets 132 are symmetrically arranged on both sides of the support ring 131, and strain resistors 134 are arranged on the humanoid elastic sheets 132.

Such a design ensures that the support ring 131 can be firmly installed on the outside of the second support part 113, providing stable support and precise positioning for the entire flow velocity detection module. The human-shaped elastic sheet 132 is symmetrically arranged on both sides of the support ring 131, and a strain resistor 134 is arranged thereon. When the fluid flows through the flow velocity detection module, pressure is generated on the human-shaped elastic sheet 132, causing it to deform. This deformation changes the resistance value of the strain resistor 134, which is then converted into an electrical signal through a circuit to achieve indirect measurement of the flow velocity. The design of the human-shaped elastic sheet improves the sensitivity to fluid pressure, making the flow velocity measurement more accurate. As a key component of flow velocity sensing, the accuracy and stability of the strain resistor 134 directly affect the accuracy of the flow velocity measurement. By rationally arranging the humanoid elastic sheet and the strain resistor 134, and optimizing the design of the support ring 131 and the second rectangular groove 133, the present disclosure improves the accuracy and stability of the flow velocity measurement, making the measurement result more reliable.

This design can accurately sense the radial pressure changes generated by the fluid on the circular elastic sheet 121, thereby providing accurate flow rate information. The number of inner ring resistors 1222 is 5, which are circumferentially and equidistantly distributed on the inner ring of the circular elastic sheet 121; the number of outer ring resistors 1223 is 5, which are circumferentially and equidistantly distributed on the outer ring of the circular elastic sheet 121; by designing that the inner ring resistors 1222 and the outer ring resistors 1223 are respectively circumferentially and equidistantly distributed on the inner ring and outer ring of the circular elastic sheet 121, the pressure changes of the fluid on different positions of the circular elastic sheet 121 can be sensed, further improving the accuracy of flow rate detection. At the same time, the staggered distribution of the inner and outer ring resistors helps to capture the changes in fluid pressure more comprehensively. The diameter of the inner ring where the inner ring resistor 1222 is located is smaller than the diameter of the outer ring where the outer ring resistor 1223 is located; the inner ring resistor 1222 is connected to the inner side of the radial resistor 1221 at intervals, and the outer ring resistor 1223 is connected to the outer side of the radial resistor 1221 at intervals, and the inner ring resistor 1222 and the outer ring resistor 1223 are staggered; wherein, one outer ring resistor 1223 is cut in the middle, and an inlet wire and an outlet wire are connected to the break, so as to facilitate the connection of the pressure-sensing resistor 122 with the external circuit to realize signal transmission and processing.

The bending parts of the strain resistor 134 are stacked at the intersection of the bending part and the vertical part of the human-shaped elastic sheet 132.

[0076] The wireless transmission module 3 of this embodiment can realize the wireless transmission of in vivo data with external terminal devices, so that patients can understand their physiological conditions in real time without having to go to the hospital for frequent examinations, thereby improving the convenience and efficiency of medical services.

[0077] Optionally, the wireless transmission module 3 is disposed between the subcutaneous fat layer and the dermis layer, which can reduce the impact of the implant on the patient and improve comfort.

[0078] Optionally, the material of the upper packaging layer 32 and the lower packaging layer 33 is polyimide 0.

[0079] Working principle of the second implantable device: 1. Pressure measurement in the pressure sensing device: The pressure-sensitive diaphragm senses the fluid pressure, converts the fluid pressure into resistance change, and collects and transmits data through the wireless transmission module. 2. Flow rate measurement in the pressure sensing device: When the fluid acts on the humanoid elastic sheet, it will cause the humanoid elastic sheet to deform (both the vertical part and the curved part will have a certain bending). At this time, the resistance of the strain resistor changes, converting the fluid speed information into resistance change, and collecting and transmitting data through the wireless transmission module. 3. Working principle of the pressure sensing system: The external terminal device collects and analyzes the in-vivo data through the wireless transceiver module to monitor blood pressure, flow rate, etc. Advantages of the second implantable device: The wireless transmission module is used to establish a signal connection with the permanently implanted pressure sensing device, collect and analyze in-vivo information, and conveniently detect the patient's in-vivo data through the external terminal device (reader device). Clinical staff, non-clinical users or patients can determine the patient's in-vivo information after appropriate training. The measurement functions of pressure, flow rate, etc. are integrated on the same substrate to provide doctors with more comprehensive monitoring data; in addition, the flow rate detection module is directly mounted on the sensor body, further reducing the size of the detection device, improving system integration, and facilitating implantation in the body.

[0080] An embodiment of the present invention provides a physiological parameter analysis method for an implantable device, which is implemented using the physiological parameter analysis system for an implantable device of the above embodiment. The method includes:

[0081] Step 1, implanting the implant device into a designated position in the body;

[0082] Step 2: Setting the acquisition and analysis module in the physiological parameter analysis device at a position corresponding to the implanted device;

[0083] Step 3: The acquisition and analysis module provides power to the implant device through the transmitting coil, and connects the first Bluetooth module to the second Bluetooth module in the implant device to realize data transmission;

[0084] Step 4: The acquisition and analysis module collects and analyzes the data collected by the implanted device. The processed data is transmitted to the display terminal via a data connection line, which is convenient for medical staff and patients to monitor physiological parameters in real time.

[0085] Optionally, the processing process of the acquisition and analysis module in step 4 includes: denoising and filtering the collected raw data, selecting the data to be analyzed after preprocessing, and converting the values ​​of these data into a longer digital string. For example, if the collected data is pressure data and the raw data is 12.3, it is expanded to 12.3000 during calculation to reduce rounding errors in subsequent calculations.
